This is one fine-looking Bluetooth earpiece, even though it's just brochure-ware so far. The Argard M10 Bluetooth headset is about the width of a nickel, but its in-ear design still packs enough battery power to last all day. The company says it'll give you three hours of talk time and 100 hours of standby time, and weighs just 5 grams.

With its microphone so far away from your mouth, who knows how good it sounds? We just wish the company would create a dual-muff version that's good for listening to music, too. It seems silly to have a Bluetooth headset with wires connecting one ear to the other. Maybe this will be the solution. Someday. – Charlie White
